Senior Mechanical Engineer – Avionics Packaging - TeraWave

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

This role sits within the Tera Wave Spacecraft Bus Electrical Power Subsystem team. We are seeking a Senior Mechanical Engineer to own the mechanical packaging for the Power Management and Distribution (PMAD) Line Replaceable Unit (LRU) — one of the most integration-intensive assemblies on the spacecraft. You will be responsible for everything the enclosure touches: card retention, thermal paths, connector access, mounting interfaces, serviceability, mass optimization, producibility, and integration flow.

You will drive this hardware from concept through formal qualification, production release, and flight support — at constellation scale.

This is a senior role. You will lead design trades, mentor junior engineers, and serve as a technical authority recognized across the broader organization. Tera Wave's production rate of thousands of units means your packaging decisions directly drive manufacturing yield, cost, and schedule. If you want to own something end-to-end and see it fly, this role is for you.

• Own the full mechanical design of the PMAD avionics enclosure from concept through qualification and production release, including enclosure structure, card retention, thermal management, connector access, mounting interfaces, and serviceability
• Define mechanical requirements, interface control documents (ICDs), and design specifications in coordination with systems engineering, electrical engineering, thermal, structures, and manufacturing teams
• Develop and maintain 3D CAD models, assemblies, part and assembly drawings, installation drawings, and other required technical documentation
• Perform structural analyses — static, modal, random vibration, shock, and fastener/joint — using both hand calculations and FEA; report margins and drive design to closure
• Design for thermal performance: conduction paths, heat spreaders, thermal interface materials, and enclosure-level heat rejection; build and correlate thermal models with test data
• Perform solder fatigue analysis (Steinberg or Engelmeier) for PCB-level components subject to thermal cycling and vibration
• Lead design trade studies for packaging architecture, material selection, and producibility optimization; document results and drive decisions
• Build and evaluate prototypes; design assembly aids, test fixtures, and tooling
• Support environmental testing — vibration, shock, thermal cycling, TVAC — including test setup, instrumentation, data review, and corrective action development
• Perform failure analysis and establish root cause and corrective action for hardware anomalies
• Collaborate with Production and Quality Engineering to disposition material defects and support DFM/DFA improvements
• Mentor and train junior engineers; review and approve designs and documentation created by other team members

• Bachelor's degreein Mechanical Engineering, Aerospace Engineering, or a closely related field
• 7 or more yearsof hands‑on experience designing ruggedized electronic enclosures or high‑reliability avionics packaging for harsh environment applications
• Demonstrated structural and thermal analysis skills, including static, modal, random vibration, and shock analysis using FEA (Ansys preferred) supported by hand calculations
• Proficiency with 3D CADfor detailed part and assembly modeling (Creo preferred), including GD&T implementation and tolerance analysis per ASME Y14.5
• Experience taking hardware…
